PSY's video featuring his horse-riding dance was posted on YouTube in July, while 'Baby' was uploaded in February 2010.

PSY's video has become a global sensation, with many people around the world mimicking his 'Gangnam Style' dance. In their October meeting, U.N. Secretary-General Ban Ki-moon, a South Korean, joked that he had to relinquish his title as 'the most famous Korean,' and tried a few of PSY's dance moves.
